It has the function of self-control temperature. The temperature control range is 5 ℃ ~ 75 ℃. It has the function of fitting. It can freely obtain the data of -273 ℃ ~ 200 ℃ material permeability, permeability coefficient, solubility coefficient, diffusion coefficient and so on. Test mode three chamber test. 3. Vac-v3 differential pressure method gas permeameter implements the principle of differential pressure method. It can test the permeability of oxygen, nitrogen, carbon dioxide and other gases. It has the function of automatic temperature control. The temperature control range is 5 ℃ ~ 75 ℃. It has the function of fitting. It can freely obtain the permeability, permeability coefficient, solubility coefficient, diffusion coefficient and other data of -273 ℃ ~ 200 ℃. Test mode six chamber test

III. 4. From the perspective of experimental intention: tensile test, pressure test, zigzag test, shear test, 90 ° peel test, 180 ° peel test, deflection test, change test, fatigue test, tear test, stiffness test, ring stiffness test, static stiffness test, technical test, bursting test, puncture test, cyclic test, safety test, durability test, high temperature test, low temperature test, high and low temperature test Protective test, limiting test, impact test, falling ball test, hardness test, bonding strength test, bolt tensile test, bonding force tensile test, sealing strength test, bonding strength test, etc; The heat sealing strength is measured according to the method of composite bag in the heat sealing strength measurement method (YBB). The parallel industry of each heat sealing part has increasingly strict requirements on automobile lightweight, low fuel consumption, low cost, low pollution, high safety and high comfort, and the average value shall not be less than 20n/15mm. Instruments available for reference from Jinan Languang Electromechanical Technology Co., Ltd. 1. The test functions of XLW intelligent electronic tensile testing machine include: heat sealing strength, tensile strength and deformation rate, breaking force and deformation rate, tear strength, shear strength, 180 degree peel strength. With puncture and opening force clamps, the opening force and puncture force tests can be carried out on the interface of large infusion bags. The function of communication with computer can be realized through professional supporting software. 2. The test functions of XLW (PC) intelligent electronic tensile testing machine include: heat sealing strength, tensile strength and deformation rate, breaking force and deformation rate, tear strength, shear strength, 180 degree peel strength, plus puncture and opening force fixture, which can test the opening force and puncture force of pull ring on the interface of large infusion bag. The instrument stroke is longer than that of XLW intelligent electronic tensile testing machine, which is more suitable for tensile testing of materials with large deformation rate. The precision is higher. The standard configuration includes a set of computer and professional software
